So my order of bearings came in from
http://www.vxb.com so it's time to start making some cuts.
The first thing I did was to cut the cutting surface out of 3/4" MDF (no pictures of that) then move on to the pipe support blocks (large) and end supports for the Y axis.
There is a slight misprint in the parts list for cnc_dtl01 and cnc_dtl02. The parts manifest list them as 1.5x8.25x16.25, when in actuality they are 1.5x8.25x32.5. So be aware of that as you're laying out your cuts on your stock.
For the 1.5" holes, I used a 1.5" hole saw and my drill press. Word of caution when cutting MDF with a hole saw... the fine dust gums up the teeth VERY quickly. So you need to make many shallow passes while withdrawing the bit from the MDF to clean it. I used a piece of scrap wood when the bit was up to clear the teeth.
Also, I only cut halfway through on the front side, then I flipped the board and finished the hole from the other side. This allowed me to remove the plug from the hole saw without having to take it apart to clear it.
Once I got the motor side support cut (both pieces) I glued it together and moved to the large adjustment blocks. I followed the same procedure for cutting the holes in the adjustment blocks as I did for the side supports.
I'll need to stop by Lowes tomorrow to find a "thread forming" tap, since all of mine are "thread cutting".. not quite sure what the difference is yet, but I've read enough of these build threads to seek one out
